Facebook is Not a Monopoly, But Should Be Broken Up (Wired) — Demand monopsonists integrate horizontally, acquiring or copying user demand adjacent to their existing demand and gaining leverage over their suppliers (and advertisers, if that’s the model). Facebook is unlikely to ever own a media production company, just as Airbnb and Uber will not soon own a hotel or a physical taxi company. But if they can, they’ll own every square foot of demand that feeds those industries. (via Cory Doctorow)
